Amazon VPC
Amazon Virtual Private Cloud (VPC) is a service that lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. It provides complete control over your virtual networking environment, including selection of IP address ranges, creation of subnets, and configuration of route tables and network gateways. This enables you to build secure, scalable, and highly available network infrastructures for applications running on AWS.
Developers should learn Amazon VPC when building applications on AWS that require secure, isolated network environments, such as multi-tier web applications, hybrid cloud setups, or compliance-sensitive workloads. It is essential for implementing network security through security groups and network ACLs, connecting on-premises data centers via VPN or AWS Direct Connect, and managing traffic flow between resources across availability zones for high availability.
